Mia,

You ought to take a look at:

James R. Hurford's article "The neural basis of predicate-argument
structure" in BEHAVIORAL AND BRAIN SCIENCES (2003) 26, 261–316

Quite an interesting read and it seems to fit well with some of ideas
you are considering with the grammar of Díne.  I get the impression
that Hurford is proposing a kind of "primitive mental representation,"
one independent of language, that makes a grammar happen.  Pretty cool
idea I think as I've been trying to find ideas or "stuff" like this to
come to an understanding of Nez Perce.

l8ter,

Phil (cayuse/nez perce)
